Chief Keef, government name Keith Cozart, was on probation for pointing a gun at Chicago police officers in 2011, and violated that probation after appearing in a promo video at a gun range.

Apparently, Sosa broke down crying at the sentencing, after the judge said he wouldn’t tolerate the teen’s “blatant violations of the court’s order.”

This isn’t the only bad news for Keef – he’s being sued for no-showing at a concert in London last month, and he’s still under investigation for involvement in the death of fellow Chi-town rapper JoJo.
